[0025] In order to prevent the material belt from deviating during the transmission process, an anti-deviation mechanism for limiting the material belt is arranged on the bag making machine body 1, which specifically includes two moving plates 3, both of which are slidably mounted on the bag making machine body 1, two buffer springs 33 are installed on one side of the moving plate 3, and a limiting plate 32 is installed on the other end of the two buffer springs 33, and the two limiting plates 32 are adapted to the buffer springs 33. A guide rod 31 is sleeved on the buffer springs 33, one end of the guide rod 31 is installed on the limiting plate 32, and the other end of the guide rod 31 is slidably mounted on the moving plate 3, and the driving mechanism includes a supporting plate 4, which is mounted on the bag making machine body 1, and a forward and reverse servo motor 41 is installed on the supporting plate 4, a driving shaft 42 is installed on the forward and reverse servo motor 41, and a gear 44 is installed on the other end of the driving shaft 42, and an installation cavity 43 is opened on the bag making machine body 1, and the gear 44 is rotatably installed in the installation cavity 43, and the upper and lower ends of the gear 44 are The two sides are meshed with toothed plates 45, and L-shaped plates 46 are installed on the two toothed plates 45. The two L-shaped plates 46 are respectively installed on the two movable plates 3. A fixing block 47 is installed on the bag making machine body 1, and the L-shaped plate 46 is slidably installed on the fixing block 47. When the bag making machine body 1 is used to cut the material belt, in order to prevent the material belt from deviating during transmission, the gear 44 is used to drive the toothed plate 45 to move, and the toothed plate 45 drives the movable plate 3 to move toward the middle, and the movable plate 3 drives the limit plate 32 to move forward, so that the limit plate 32 can be easily moved to a position suitable for the width of the material belt for limiting. At the same time, the setting of the buffer spring 33 can effectively limit the material belts of different widths, and avoid the limit plate 32 from squeezing the material belt too hard, causing wrinkles on the edge of the material belt, and the forward and reverse servo motor 41 is used to provide power for the movement of the movable plate 3, so that the position of the limit plate 32 can be effectively adjusted back and forth at any time.

[0026] The working principle is as follows: when the bag making machine body 1 is used to cut the material strip, the cylinder on the cutting knife assembly 2 is used to drive the pressure block 2 to squeeze the material strip downward. At the same time, in the process of transmitting the material strip, in order to prevent the material from deviating, the forward and reverse servo motor 41 on the support plate 4 is used to drive the driving shaft 42 to rotate, and the driving shaft 42 drives the gear 44 in the installation cavity 43 to rotate, and the gear 44 drives the tooth plate 45 to move toward the middle, and the tooth plate 45 drives the L-shaped plate 46 on the retaining block 47 to move toward the middle, and the L-shaped plate 46 drives the moving plate 3 to move, and the moving plate 3 drives the guide rod 31 to move, and the guide rod 31 drives the limit plate 32 to move toward the middle, so that the limit plate 32 can be conveniently moved to a position suitable for the width of the material strip for limiting, so as to prevent the material strip from deviating during the transmission process. At the same time, the setting of the buffer spring 33 can be used to accommodate material strips of different widths. The limiting plate 32 can also effectively prevent the limiting plate 32 from squeezing and folding the edge of the material belt when limiting the material belt, and then driving the cutter to cut the material belt.

The loading plate 53 drives the product to move upward. In the process of moving upward, it will first drive the receiving plate 55 to rotate into the limiting groove 54. The rotation of the receiving plate 55 drives the rotating shaft 57 in the rotating cavity 56 to rotate, and the rotating shaft 57 drives the torsion spring 58 to deform.
